Status and Trends of Experimental Research on Mandarin Chinese Phonetic Acquisition Bias: A CiteSpace-Based Visualization Exploration

This paper comprehensively analyzes the relevant literature in the China Knowledge Network (CNKI) database in the past 20 years, takes the final 687 pieces of literature as the data source, combines the knowledge graph tool CiteSpace, and follows the principle of combining the macro and micro, historical and cooccurring, to quantitatively and statistically analyze the domestic literature on the study of Mandarin phonetic acquisition, and to summarize current status of the study and the trend, the learners of the Chinese language, and the main types of bias in phonetic learning from multiple levels and viewpoints, countries, as well as the main types of bias in phonetic learning were sorted out and summarized from multiple levels and perspectives, in order to sort out the hotspots of the research on the Mandarin Chinese phonological acquisition in China and its developmental vein. It was found that the core of the research in this field focuses mainly on tones, affricates, bias analysis, and teaching strategies, which are studied with the help of acoustic experiments and speech analysis techniques. Under the trend of multidisciplinary integration, experimental research on phonetic acquisition is expected to achieve more in-depth and comprehensive results by expanding the research field, integrating multimodal research methods, and deeply exploring the bias characteristics of second language learners.
